03/07/2013 02:25---=====================================================================-- THIS IS THE FIRST SPE COMPARISON PROBLEM,"COMPARISON OF SOLUTIONS TO A-- THREE-DIMENSIONAL BLACK-OIL RESERVOIR SIMULATION PROBLEM", REPORTED-- BY AZIS AND ODEH AT THE SPE SYMPOSIUM ON RESERVOIR SIMULATION ,-- JANUARY 1981. IT IS A NON SWELLING AND SWELLING STUDY. A REGULAR-- GRID WITH TWO WELLS (INJECTOR AND PRODUCER)AND A IMPES SOLUTION METHOD-- IS USED FOR THIS SIMULATION.THE PRODUCTION IS CONTROLLED BY FLOW RATE-- AND MIN. BHP. OIL RATE, GOR, PRESSURE AND GAS SATURATION ARE TO BE REPORTED.-- =====================================================================RUNSPECTITLE ODEH PROBLEM - IMPLICIT OPTION - 1200 DAYS

GRID ================================================================-------- IN THIS SECTION , THE GEOMETRY OF THE SIMULATION GRID AND THE-------- ROCK PERMEABILITIES AND POROSITIES ARE DEFINED.-------------------------------------------------------------------------- THE X AND Y DIRECTION CELL SIZES ( DX, DY ) AND THE POROSITIES ARE-- CONSTANT THROUGHOUT THE GRID. THESE ARE SET IN THE FIRST 3 LINES-- AFTER THE EQUALS KEYWORD. THE CELL THICKNESSES ( DZ ) AND-- PERMEABILITES ARE THEN SET FOR EACH LAYER. THE CELL TOP DEPTHS-- ( TOPS ) ARE NEEDED ONLY IN THE TOP LAYER ( THOUGH THEY COULD BE.-- SET THROUGHOUT THE GRID ). THE SPECIFIED MULTZ VALUES ACT AS-- MULTIPLIERS ON THE TRANSMISSIBILITIES BETWEEN THE CURRENT LAYER-- AND THE LAYER BELOW.
